Northern Long-eared Bat
This map shows the northern long-eared bat range overlain with forested areas. Because northern long-eared bats require trees for roosting during summer, the forested areas within the range indicate where this bat may occur during times when it is not hibernating (spring through fall).
This map differs from the previous versions in that the range in the United States is depicted by county. We are using counties to identify the range so that it matches the range used to identify the WNS buffer zone used for the northern long-eared bat 4(d) rule.
